摘要:

目的 探讨基于视听觉和运动反馈的脑机接口(BCI)结合经颅直流电刺激(tDCS)对脑卒中患者上肢功能的疗效。
方法 2023年3月至10月,徐州医科大学附属徐州康复医院和徐州市中心医院住院的脑卒中患者45例,随机分为BCI组、tDCS组和联合组,每组15例。3组均接受常规康复治疗,BCI组增加BCI,tDCS组增加tDCS治疗,联合组先行tDCS治疗,然后立即进行BCI,共4周。治疗前后采用Fugl-Meyer评定量表上肢部分(FMA-UE)、上肢动作研究量表(ARAT)和改良Barthel指数(MBI)进行评定,测量脑电图δ-α比(DAR)和功率比指数(PRI)。
结果 治疗后,3组FMA-UE、ARAT和MBI评分均较治疗前显著提高(|t| > 5.350, P < 0.001),联合组最优(F > 3.366, P < 0.05),DAR和PRI均较治疗前显著减小(|t| > 2.208, P < 0.05),联合组最优(F > 5.224, P < 0.01)。
结论 基于视听觉和运动反馈的BCI结合tDCS可进一步改善脑卒中患者上肢运动功能,提高日常生活活动能力。

Abstract:

Objective To explore the effect of brain-computer interface (BCI) based on visual, auditory and motor feedback combined with transcranial direct current stimulation (tDCS) on upper limb function in stroke patients.
Methods From March to October, 2023, 45 stroke inpatients in Xuzhou Rehabilitation Hospital and Xuzhou Central Hospital were divided into BCI group (n = 15), tDCS group (n = 15) and combined group (n = 15) randomly. All the groups received routine rehabilitation, while BCI group received BCI training, tDCS group received tDCS, while the combined group received tDCS and followed by BCI training immediately, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Action Research Arm Test (ARAT), modified Barthel Index (MBI) and delta-alpha ratio (DAR) and power ratio index (PRI) of electroencephalogram before and after treatment.
Results The scores of FMA-UE, ARAT and MBI increased in all the groups after treatment (|t| > 5.350, P < 0.001), and all these indexes were the best in the combined group (F > 3.366, P < 0.05); while DAR and PRI decreased in all the groups (|t| > 2.208, P < 0.05), they were the best in the combined group (F > 5.224, P < 0.01).
Conclusion BCI based on visual, auditory and motor feedback combined with tDCS can further improve the motor function of upper limbs and the activities of daily living of stroke patients.
